LinkedIn Comments Strategy: How to Get Noticed Without Posting

Most people think LinkedIn growth requires a constant stream of original posts. It doesn't.

Some of the fastest-growing LinkedIn accounts barely post at all. Instead, they've mastered the art of LinkedIn comments — showing up consistently in conversations that already have an audience, adding genuine value, and letting their name spread organically.

This guide breaks down exactly how a smart LinkedIn comments strategy works, why it's one of the most underrated growth tactics on the platform, and how to do it without sounding like a professional LinkedIn commenter (yes, that's a thing, and it's cringe).

Why LinkedIn Comments Are a Growth Engine

Before getting into tactics, it helps to understand why commenting works so well.

When you leave a comment on someone's post, it doesn't just sit there quietly. LinkedIn surfaces that comment to your connections and followers — effectively borrowing the reach of the original post's audience. If the post has 10,000 impressions and you leave a standout comment, a meaningful slice of that audience sees your name, your headline, and your take.

That's free distribution. And unlike posting, it takes two minutes instead of two hours.

There's also a compounding effect. The more you comment thoughtfully on posts in your niche, the more people start to recognise your name. They visit your profile. They connect. Some become followers. Over time, you become a known voice in your space — without ever hitting "post" yourself.

The Four Types of LinkedIn Comments (And Which Ones Actually Work)

Not all comments are created equal. Here's how to think about them:

1. The Empty Agreement (Don't Do This)

"Great post!" "So true!" "Totally agree!"

These contribute nothing. They don't add to the conversation, they don't display expertise, and they frankly annoy anyone who's paying attention. LinkedIn's algorithm also deprioritises low-effort engagement — so they may not even be worth the three seconds it takes to type them.

2. The Contrarian (Handle With Care)

Disagreeing with a post can generate serious engagement — LinkedIn loves a debate. But do it with data, nuance, and respect. "I'd actually push back on this — in my experience, [alternative take] because [reason]" is powerful. "This is completely wrong and here's why" is not.

3. The Value-Add (This Is Your Goal)

The best LinkedIn comments add something the original post didn't include. A different angle. A real example. A tool or resource that's genuinely useful. A follow-up question that deepens the conversation.

These comments get likes. They get replies. They get profile visits. This is the format to default to.

4. The Story (Use Sparingly, High Impact)

A short personal story triggered by the post — two to four sentences max — can outperform everything else. Why? Because it's unexpected. Most comment sections are full of opinions and platitudes. A brief, specific story stands out immediately.

How to Build a LinkedIn Comments Strategy That Actually Works

Step 1: Choose the Right Accounts to Engage With

This is where most people go wrong. They comment on whoever happens to appear in their feed, which means commenting on randoms with zero strategic overlap.

A better approach: identify 15–25 creators in your niche who post regularly and have an engaged audience. These should be people your ideal connections and followers already follow.

Make a shortlist. Check in on their content daily or a few times per week. Be one of the first to comment when they post (more on why that matters below).

Look for:

Accounts with 3,000–30,000 followers (enough audience, not so large your comment disappears instantly)
Posts that typically get 30+ comments (active conversations are better for visibility)
Creators whose audience overlaps with who you want to attract

Step 2: Be Early

LinkedIn's comment section is roughly chronological. The first handful of comments on any post get far more views than comments left hours later when the post has stopped being amplified.

Turn on notifications for your shortlist of creators. Aim to be in the first five to ten comments on their posts. Even a solid comment that arrives 12 hours late is mostly invisible.

Step 3: Lead With a Specific Observation

Generic openers kill comments. Instead of "Great point about X", try:

"The part about [specific thing] hit me differently because [specific reason]."

Or: "You buried the most important insight in bullet three — [paraphrase]. That deserves its own post."

Starting with a specific detail signals that you actually read the post. People notice. The original poster especially notices — which matters for building the relationship.

Step 4: Add One Concrete Thing

After your observation, add one thing: a data point, a contrasting experience, a related framework, a tool that solves the problem being discussed. One thing. Not five.

Long comments get skimmed or ignored. Comments that are 3–6 sentences and clearly add something get read, liked, and replied to.

If you write a lot of LinkedIn content yourself, a tool like the LinkedIn Hook Generator can help you craft openers that cut through — and that same skill translates directly to writing comment openers that grab attention.

Step 5: End With a Question (Optional, But Effective)

A comment that ends with a genuine question invites a reply from the original poster. That reply creates a visible thread, which gets more exposure. It also signals to others that you're curious and engaged rather than just self-promoting.

The question has to be real, though. "What do you think?" is lazy. "Have you found this works differently in B2B SaaS vs. services?" is specific and shows you're paying attention.

LinkedIn Comments Strategy for Founders and Marketers

If you're a founder or a marketer building a personal brand, commenting is particularly powerful because it lets you get in front of your target audience before they know they need you.

Here's a practical structure for this:

The 30-minute commenting sprint:

Open LinkedIn
Check your shortlist of 15–25 creators
For any new posts, leave a thoughtful 3–5 sentence comment
Reply to anyone who responded to your previous comments
Done

Repeat three to four times per week. After 30 days, track your profile view trends. Most people who do this consistently see a meaningful lift without posting a single original piece of content.

You can pair this with occasional original posts when you have something genuinely worth saying. But the commenting habit is the foundation. And when you do post, the relationships you've built through commenting will show up early to engage — which is exactly what the LinkedIn algorithm rewards.

Speaking of which: if you do want to start posting, the LinkedIn Post Generator makes it straightforward to create posts that match your voice without starting from a blank screen every time.

What to Comment On: Content Categories That Work

You don't have to comment on everything. Some content categories generate better conversations than others for building visibility.

High-value targets:

Contrarian or provocative takes (these have active comment sections)
Posts sharing a personal failure or lesson (people engage more emotionally)
Posts asking for opinions or experiences (natural invitation to participate)
Industry data or research shares (room to add context, push back, or expand)
Posts in your direct niche that are getting traction but lack nuanced discussion

Skip:

Purely promotional posts (brand content, product announcements)
Viral memes or generic "motivation" content (the audience isn't your audience)
Posts from people who never engage with comments (one-way broadcasters)

The LinkedIn Comments Mistake That Tanks Your Reputation

There is one move that will get you silently blacklisted by every serious LinkedIn creator: dropping your own links in someone else's comments.

"Great post! I wrote about this too — [link]" is the LinkedIn equivalent of walking into someone's party and handing out your own business cards to their guests.

Don't do it. Not in the first comment, not as a reply, not even if it's genuinely relevant. The one exception: if someone explicitly asks for a resource, and you have a great one, you can share it — but frame it as a recommendation, not a promotion.

Tracking Your LinkedIn Comments Strategy

Most people never measure this, which is why most people never improve it.

Every few weeks, do a quick audit:

Which of your comments got the most likes and replies?
Which creators responded to you?
What topics or comment styles performed best?
Did your profile view count move?

LinkedIn doesn't make this easy to track natively, but you can keep a simple log. Note what you commented on, roughly how many reactions it got, and whether it led to a connection or conversation.

Over time, you'll identify the content categories, creators, and comment formats that work best for your audience. Then you do more of that.

Using Hooked AI to Write Better LinkedIn Comments

Yes, an AI tool can help you write better comments — if you use it correctly.

The goal isn't to outsource your thinking. It's to get past the blank-page friction when you know what you want to say but aren't sure how to open.

Try this: paste the post text into the LinkedIn Hook Generator with a prompt like "write me an opening line for a comment that challenges the conventional take here." Use the output as a starting point, then edit it into your actual voice.

Once you've written a comment you're happy with, you can run it through the LinkedIn Text Formatter if it's a longer reply — clean formatting makes long comments far more readable.

The combination of strategic targeting, consistent timing, and sharp comment writing is what separates the people who grow through commenting from those who try it for two weeks and give up.

LinkedIn Comments Strategy: Quick-Reference Checklist

Before you leave a comment, run through this:

✅ Did I actually read the full post?
✅ Does my comment add something new (not just agree)?
✅ Is it specific enough that it couldn't apply to any post?
✅ Is it under 6 sentences?
✅ Does it invite a reply or further thought?
✅ Am I commenting early enough to be visible?
❌ Am I dropping a self-promotional link? (Don't.)

That's it. Save this list. Use it every time.
